WATER-HEATER.

Specification of Letters Patent.

Patented Apr. 27, 1920.

Application filed March 22, 1918. LSerial No.. 223,881.

To nl! whom 'it may concern i Bc it known that I, CapvrN 1). Tanning a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented new and uscful Improvements in VateoHeaters, ot

which the following is a speciticaticn.

This invention relates to an auxiliary water heater which is adapted to be used in conjunction with an ordinary main or primary steam or hot water boiler and capable of indirectly usingr the heat of the water in the boiler for heating secondary water which is to be used for different purposes, and which also permits of heating the water which is to be used either directly by means of a gas or similar burner and also permits suoli serondary water to be heated dilectiy and indirectly simultaneously by the combined effect of this burner and by the pri mary water of the boiler.

The purpose of this invention is to pro `vide a heater capable of accomplishing this purpose which is simple in construction7 cflicicn't in operation and capable of being produced at comparatively low cost.

ln the accomlninying drawings:

Figure l is an elevation of a boiler and storage tank and associated parts connected with a water heater embodying my improvements. Fig. 2 is a vertical section of the water heater embodying my invention`r on an enlarged scale. Figs. 3 and 4 are horixontal sections, taken ou the correspondingly numbered lines in Fig. 2.

Similar characters of reference refer to like parts throughout the several views.

The boiler 1 shown in the drawings is merely an example of one suitable for use in connection with my improvements :ind the same may be either utilized for heating primary water or producing steam for which purpose the same is provided at its top with an outlet pipe Q which is adapted to be connected with the different fixtures to which steam or primary hot water is to be supplied. Adjacent to the' boile is arranged a water storage tank 3 which may also be of any suitable construction and to which fresh water may be supplied in yarious ways7 for instance, by means of a1 service or main supply pipe 4 extending downwardly through the top of this tank and terminating near the bottom thereof.

The water heater which is associated with this boiler and tank and which contains my invention is preferably construeted'as follows 5 represents an inner wall which incluses a space formingr an inner heating chamber t5, this chamber being preferably arranged in an upright position and provided at its upper end with a water inlet 7 and at its lower end with a water outlet 8. The inlet of this inner heating chamber is connected with the upper part of the water space of the boiler by means of an upper si: poly pipe t? which contains, a valve 1() while the lower outlet thereof is connected with the lower part of the water-.space of the boilerby means of a lower or return pipe 11. 'f

Around the inner wall of the auxiliary heater is arranged an outer wall 12, which forms between the same and said inner wall an outer heating chamber 13.v The latter is provided at its upper end with. an outlet 14 and atits lower end with an inlet 15, this outiet and inlet beingr preferably formed on one side of the outer wall. The outlet lllis connected in any suitable manner with the different ,fixtures which are to be served with secondary hot water` for instance as shown in thedrawings. this is accomplished. Ly means of piping which comprises a pipe section 1G extending from the outlet 14 to the upper end ofthe water storagetank, a pipe section 17 extending from the Water tank to the fixtures from which secondary hot water is to be wlthd "awn, and another section 18. extending to a radiator or similar device which is intended to heat the surrounding spaee by means of hot water. The inlet of the outer heating chamber may receive water from various sources. the piping shown in the drawings being designed to transfer water from the tank to this outer chamber and also return water from the outlet of the radiator to the outer heating chamber, this being preferablyy accomplished by connecting the lower end of the water -tank with the Water inlet of the outer heating el'iambcr by means of atank return pipe 19 and conneeting this return pipe with a radiator return pipe .20 leading from the outlet of the radiator.

As the' water in the boiler is heated a part thereof passes through the upper Supply pipe 9 into the upper part of the inner heatlng chamber and as it becomes rcooler it f n lia mitm hrwllingj rhaimhsr in ii-,inpilwinrv thaj saune pus-Ps upherinner-1 muli 'return pipe 1S! in the lfriiifr nini Ulf the outrr heating' rhamnrr nml the. cooled water fram the rmlizitnr ula-in returns through the radiator return pipe :2U unil tank pipe ifi tn 'th-f3 out@ heating ffl'iiimhar n that a cfmf-tiit secondary cirriiiuion (if heizitni water is maintziiinil thrnngh thin Miter czfcziinher :iii-:l wiilrnr mnh, and uis@ thrrnigll the rabiutnr whim th( lnitrr is in use.

In ni'f'lvr tn utilize tha heilt of thu. burner linnn tn the heir-t advantage, the (inter will of 1hr, outer hriiiing chzmihcx is preferably 1s compelled to take so constructed thaty the heat of this flame a tortuous course in passing from the burner through the space between the casing and ti e outer chamber W'all to the vent pipe. his is preferably accomplished by constructing the outer chamber wall in the form fof a plurality of superimposed compartments 35 which are elongated or of oblong torm in horizontal compartment, each of these sections having its opposite narrow ends arranged close to the body of the casing while the opposite wide sides thereof are separated byintervcning passages from said body, and the several compartments being arranged so that the narrow ends of one compartment are vertically in line with the passages 36 formed between the wide sides of adjacent compartments and the body of the casing, as shown in Figs. 2, 3 and 4. Due to this construction the heat'from the burner is compelled to make a partial turn as it passes each of the' outer wall compartments and thereby causes the heat to be utilized more effectively and the secondary wiater in the outer heating chamber to be heated more efficiently before the products of combus tion escape through the vent pipe Si.

lNhen the main boiler is not utilized in the summer time for heating purposes the secondary water in the outer heating chamber may be heated solely by means of the flame from the burner. It will therefore be apparent that by the use of this auxiliary heater it is possible to obtain hot water for domestic or other purposesat all times of the year inasmuch as the secondary water may be heated either by the burner 33, or by the main boiler7 or by utilizing both of said these heating means, thereby enabling hot water to be obtained for domestic orI other purposes at a minimum cost during the entire year regardless of Weather conditions.

This auxiliary heater can be installed in connection lwith an ordinary boiler, water storage tank and the fixtures which are to be supplied without requiring any radical change in` the pipin or connections and owing to the simplicity of the .construction of this auxiliary heater the advantages obtained from the same can be realized at comparatively small cost.
